Merge a Black Hole Tier List
Rankings for income, raiding, and overall value — re-checked after every Sunday update.
This Merge a Black Hole tier list ranks black holes for Cash income, raiding, and overall account progression in the Roblox experience developed by XAF Games. Merge games live and die by balance patches — read the disclaimer below before spending Stars, rebirth points, or hours merging a hole that next week’s update might nerf.
Use this hub to choose a focus, then drill into specialized lists: cash income rankings for offline farming and raiding rankings for PvP base offense and defense.
Early meta disclaimer
Merge a Black Hole is early-meta. XAF Games ships weekly Sunday updates that adjust merge costs, hole stats, raid damage, Star Shop stock, and rebirth multipliers. Tier placements here reflect community testing in the current patch cycle — not permanent truth.
What that means for you:
- S-tier today may be B-tier next Sunday if a hole’s offline Cash or raid HP changes.
- New holes added in updates start unranked until players test merge chains and raid interactions.
- Rebirth scaling can flip rankings — a mid-tier hole with strong multipliers beats a raw S-tier pre-rebirth.
- This wiki updates tier pages after patch notes appear on the updates tracker.
If you are returning after a break, re-read both sub-lists before selling or merging legacy holes. When in doubt, keep one copy of each high-tier hole until rankings stabilize mid-week.
How we rank black holes
Scores combine measurable in-game performance and practical progression value — not rarity alone.
Income weight — Offline and active Cash per second at equal upgrade level, including merge cost efficiency.
Raid weight — Steal priority, defensive hold time when placed in locked bases, and synergy with raid tools.
Accessibility — How quickly a new player obtains the hole after redeeming MERGE code Cash and following the getting started guide.
Star Shop synergy — Some holes scale disproportionately with Star boosts; noted in cash and raid sub-pages.
Patch volatility — Recently buffed or nerfed holes carry a tilde (~) in tables until stable for two Sundays.
Overall tier list (current patch)
General-purpose ranking when you want one hole line before specializing. See specialized lists for min-max detail.
| Tier | Black holes (examples) | Summary |
|---|---|---|
| S | Void Collapse, Event Horizon Prime, Singularity Crown | Best blend of income and raid threat; prioritize merges |
| A | Gravity Well MK-II, Dark Matter Serpent, Accretion Drake | Excellent specialists slightly below S in one mode |
| B | Neutron Maw, Pulse Ring, Cash Comet | Solid mid-game; replace after first rebirth |
| C | Starter Abyss, Mini Vortex, Dust Hole | Tutorial tiers — merge up quickly |
| D | Broken Shard, Glitch Remnant | Placeholder or deprecated — do not invest Stars |
| F | Scrap Singularity | Actively misleading stat tooltip — avoid |
Names mirror common community labels; exact in-game names may differ slightly by locale string. Cross-check tooltips after Sunday patches.
S-tier breakdown
Void Collapse — Current king of flexible bases. Offline Cash rivals dedicated farmers on the cash income list while surviving longer than pure DPS holes when raiders hit a locked base. Merge priority after mid-game.
Event Horizon Prime — Raid-first with acceptable income. Place in forward base slots during raid windows. Pairs with defensive layouts in the raiding guide.
Singularity Crown — Late rebirth reward. Expensive merge chain but scales with multipliers better than any A-tier. Not for day-one players unless you boost with FREESTARS Star Shop picks from the codes hub.
A-tier and below (quick notes)
Gravity Well MK-II — Nearly S for offline Cash; weak raid HP keeps it A. Dark Matter Serpent — Opposite profile: raid monster, mediocre idle income. Accretion Drake — Balanced budget option pre-rebirth.
B-tier holes bridge early tutorial units to A-tier chains. Merge through them — do not Star upgrade.
C-tier exists to teach merge mechanics from the merge guide. Speed-run merges using MERGE promo Cash.
D/F tiers include deprecated event holes nerfed into irrelevance. Check expired codes event timelines if you wonder why a favorite vanished from S-tier discussion.
Income vs. raiding: pick your path
Idle farmers should follow cash income tiers first — maximize offline Cash, lock base, rebirth on income thresholds.
Raiders prioritize raiding tiers — offensive steal speed and defensive stall matter more than raw Cash per second.
Hybrid players use this overall list, then split investments 70/30 toward their preferred sub-list after first rebirth.
Stars, codes, and tier climbing
Stars from FREESTARS, achievements, and Star Shop bundles accelerate tier jumps. Spend on holes confirmed S-tier in the current patch — not cosmetics. Redeem all working codes before big merge sessions.
Rebirth resets some holes but keeps multipliers. Rebirth when A-tier income eclipses merge cost of chasing S-tier — formulas change Sundays; verify in-game UI.
Automation note
Players using auto merge scripts should configure tier caps at your list goal — never merge past S-tier holders into fodder. Auto lock protects ranked defensive holes overnight.
Maintenance schedule
We review tiers every Sunday after XAF Games patches. Major reworks get notes on updates. Disagree with a placement? Test merge cost per Cash gained and raid time-to-steal — early meta rewards data over hype.

Frequently Asked Questions

No — it is a community wiki resource for XAF Games' Merge a Black Hole, updated after Sunday patches. In-game tooltips and developer notes on official links override fan rankings when they conflict.
Why does the tier list say early meta?
Weekly Sunday updates change hole stats, merge costs, and rebirth scaling. Rankings stabilize mid-week but can shift every patch — always check updates before big investments.
Should I focus on cash or raiding tiers?
Idle players should read cash income tiers first. PvP-focused players start with raiding tiers. Hybrid players use this hub overall list until first rebirth.
How often is the tier list updated?
We aim to review every Sunday after XAF Games maintenance, plus emergency hotfixes noted on the updates page.
Do promo codes change tier progression?
MERGE (1k Cash) and FREESTARS (2 Stars) from the codes hub accelerate early merges but do not change tier placements — they help you reach ranked holes faster.
